????并列第3：石油與天然氣開采

????由于美國增加了原油和頁巖氣的產(chǎn)量,，以便減少對進(jìn)口的依賴,，這一行業(yè)在美國得以飛速發(fā)展。該行業(yè)與去年一樣排在榜單第三,，純利潤率則由15.1%升至16.4%,。

????Tied 3. Oil and gas extraction

????Oil and gas are booming in the U.S. thanks to increased production of crude oil and shale gas that is making the country less reliant on foreign imports. As such, this industry sector remained in third place with a profit margin that increased from 15.1% to 16.4%.
